Struct: TTaggedQuery

template <class... T>
struct TTaggedQuery;

Systems world tagged query iterator.

This is basically an extension to TQuery that allows to ensure additional components without the need for reading them - useful for tag components (ones that just mark actors and do not store any data).

Note

User should rather construct queries with USystemsWorld::TaggedQuery instead o constructing queries by hand.

Example

systems_world_tagged_query

Methods

  • Iter

    public:
TQuery<T...> Iter() const;

    Constructs TQuery from requested actor components and tag components.

  • TTaggedQuery

    public:
TTaggedQuery(
    USystemsWorld* InSystems
);

    Constructs tagged query from systems.

    An equivalent of calling USystemsWorld::TaggedQuery

  • With

    public:
